ALARM-CLOCK.

Specification of Letters Patent.

Patented Aug. 10, 1999.

Application led. February 24, 1909. 'Serial No. 479,747.

To all whom it may concern:

Be it known that l, Josnrn B. OoNNoLLY, a citizen of the United. States,residing at ldlashington, in the District of Columbia, have inventedcertain new and useful lmprovements in Alarm-Clocks, of which thefollowing is a specitication.

rThis invention has relation to alarm clocks and has for its object theprovision of novel means for giving an audible signal at anykpredetermined time, as is customary With alarm clocks ot the usualcharacter, and also for visually indicating the particular purpose forwhich the alarm has been caused to sound at a particular time.

A further object of the invention is to provide novel means whereby thealarm actuating and alarm setting devices are simultaneously operated bythe manual movement of a single actuating p art, such as a lever orWheel operatively connected to the alarm actuating and the alarm settingdevices.

in carrying my invention into effect, l preferably employ an alarm`clock ot Well knot/'n construction having the usual parts and applythereto the mechanism hereinafter described in detail and adapted toaccomplish the objects of this invention.

As the construction and operation of alarm clocks ot the ordinarycharacter are Well understood will not specifically describe all theparts of the same, but ceniine the description of the clock to suchparts as coact with my present improvements, and specifically describethe latter.

in the accompanying drawing: Figure 1 is a side elevation of an alarmclock With my improvements applied thereto. Fig. 2 isa front elevationof the clock shown in Fig. 1. Fig. 3 is a front elevation of a clock ofmodiiied construction also embodying my impiovements. Fig. 4 is a rearelevation ot the clock shown in Fig. 3. Fig. 5 is a fragmentarysectional view on an enlarged scale of a portion et the mechanism commonto both of the clocks shown in the other figures. Fig. 6 is aperspective view of a modiiied form of memorandum tablet to be used withthe clock shown in Figs. 1 and 2. 7 is a plan view ot the clock with thedial and case removed. Fig. 8 is a front elevation of the same with thecase, the dial and the hands removed.

The clock Works are contained in a casing 1 supported by legs 2 andhaving the dial 3 the hour ,hand 4, minute hand 5, seconds hand 6.

An alarm bell 7 is mounted. on casing 1 and the hour hand arbor S isprovided on its rear end with the usual button or thumb-nut 9 iorsetting the hands, While the shaft 10 of the main spring is providedwith a key 11, and the time keeping mechanism is operably connected withthe alarm let-ott' mechanism in the usual manner and as shown in Figs. 7and 8, all these parts being ofthe usual or any desired construction.

Upon the back of the clock a hollow boss 12 is mounted and secured, thisboss having a central opening through which thc hour hand sha'l't orarbor 3 passes loosely, and upon this boss is loosely mounted a gearWheel 13 which carries an arm 14 that is attached to the Wheel 13 and isbent around the side of the clock and terminates at the iront Oi theclock Where it carries a hand or pointer 15 adapted to point to thefigures at the edge of the dial. A nut 16 serves to sustain the Wheel 13at its proper position on the boss While permitting it to be turnedfreely thereon through the medium oi arm 14. The gear Wheel 13 mesheswith an idler 17 mounted on the back ot' the clock and said idler 17meshes With a gear Wheel 18, carried on and rigidly attached to thealarm setting shaft 1Q, the Cear Wheels 13 and 18 being of exactly thesame diameter so that the Wheel 13 will complete a revolution at eachcomplete revolution oi' the wheel13, and Will, o1' course, make apartial revolution oi' equal extent With each partial revolution ofWheel 13. A third gear Wheel 2O is rigidly attached to the alarm Windingsha'lt 21, and meshes With the idler 17 the Wheel 2O being oi anydesired size relatively to the Wheel 13. The alarm operating mechanismof which the sha'lt 21 is a part, is so constructed that the shal't 21is permitted to turn in one direction only and does not rotate reverselyto the Winding movement when the alarm goes oli', but as this is acommon and Well known construction, the alarm mechanism need not be moreparticularly described.

In Figs. 1 and 2 o'l` the drawing a small plate or tablet 22 is carriedby the arm 14, this tablet being made of some material that will readilyreceive slate pencil, lead pencil, or other marks that can be easilyerased, such material, for instance, as slate, ground glass, orroughened celluloid or the like. The tablet is supported in a frame 23which is attached to the arm 14 by clips 24 so that the frame and tabletcan be readily removed and replaced when it is desired to write on thetablet or erase the writing from the same.

In the modii'ied form shown in Fig. 3 of the drawing the plate or tablet22 is dispensed with and instead of the same I provide a stationaryannular writing surface 25 which surrounds and partially covers thenumerals on the dial and which can be easily formed by roughening orgrinding the outer portion of the glass face which usually covers thedial, although I prefer to make this writing surface of somewhat largerdiameter than the dial so as to give ample writing space to receive thedesired memoranda.

In the modified form ol" memorandum tablet shown in Fig. 6 a block orpad of sheets ol' paper 26 is secured to a backing 27 and the latter isprovided with spring clips 28 by means of which the tablet can bereadily attached to the arm 14. Each sheet can bear numbers indicatingthe day of the month and each sheet after being used can be torn off andpreserved thus serving as a record of the days engagements.

rPhe alarm winding and setting mechanism of the clock shown in Figs. 1and 2 is exactly the same as that of the clock shown in Figs. 3 and 4,such mechanism being illustrated in Figs. a and 5 and having beenhereinbefore described.

The operation is as follows: 'The memoranda of various matters requiringattention at particular times is written either on the tablet 22 or onthe surface 25 or on one of the sheets of the block or pad 26, and thearm 14 is moved from right to left, that is in a reverse direction tothe movement of the hands of the clock until the hand or pointer 15points to the hour and minute of the iirst memorandum. Vlfhen the hourhand reaches a point opposite the hand or pointer 15, the alarm wil besounded and a glance at the tablet 22 or he Writing surface 25 or theouter sheet or pad 26 will show what particular matter requiresattention. After the alarm has gone off the arm 14 is moved in thedirection of the arrow until the hand or pointer 15 points to anotherhour, this movement simultaneously winding an d setting the alarm andthus making ready for the sounding of the alarm Without furtherattention or manipulation. The arm 14, it is to be noted, is alwaysmoved in a direction opposite to the movement of the hands, and thus if,for instance, the rst alarm soun ds at two oclock and it is desired tohave the next alarm sound at three oclock, the arm 1d is turned througheleven twelfths of a circle, thus bringing the hand or pointer 15opposite the numeral III on the dial.

I claim:

1. rlhe combination with an alarm clock,

of a movable arm connected to and adapted to simultaneously operate thealarm winding and alarm setting mechanism and a memcrandum tabletcarried by said arm.

2. rIhe combination with an alarm clock, of a movable arm having apointer adapted to successively point to the figures on the dial of theclock, and a memorandum tablet carried by said arm.

3. rIhe combination in an alarm clock of time keeping mechanism and timeindicating means for keeping an d indicating the time of day and alarmmechanism adapted to be let off by the progressive and uninterruptedmovement of the time keeping mechanism, with a movable arm and meanscontrolled by the movement of said arm for simultaneously winding andsetting the alarm mechanism.

li. In an alarm clock embodying time keeping mechanism and timeindicating means adapted to keep and indicate the time of day and alarmmechanism adapted to be let oli' by the progressive and uninterruptedmovement of the time keeping mechanism, said alarm mechanism includingthe alarm operating and alarm setting mechanism, and means forsimultaneously Winding and setting the alarm.

5. In an alarm clock embodying time keepingv mechanism and timeindicating means for keeping and indicating the time of day and. alarmmechanism adapted to be let olf by the time keeping mechanism while thelatter continues in operation, said alarm mechanism including the alarmoperating and alarm setting mechanisms, means for simultaneously windingand setting the alarm and a pointer adapted to indicate the time atwhich the alarm will sound.

6. In an alarm clock embodying time keeping mechanism and alarmmechanism adapted to be let olf by the time keeping mechanism, thecombination with the dial and a movable pointer to indicate the time atwhich the alarm will sound, of a memorandum tablet carried by the clockarranger in proximity to the dial of the clock.

7. T ie combination with time keeping mechanism and time indicatingmeans adapted to keep and indicate the time of day and alarm mechanismadapted to be let olf y the progressive uninterrupted movement of thetime keeping mech sin, oi' means whereby the actuating spring of thealarm mechanism will be wound by the movement of the alarm settingmechanism.

In testimony whereof I have a'fl'lxed my signature, in presence of twowitnesses.
